I used this lobster claw to replace the broken one on a sterling silver bracelet that I purchased from a jeweler. The chain on the bracelet is substantial and it would have cost a lot to repair. But this lobster claw closure and the two sterling silver locking jumprings that I purchased from your site did the trick. It cost me 1/4th of what the jeweler charged. The lobster claw was sturday enough to withstand the pressure of keeping the bracelet secure at a reasonable cost. Thank you for a well performing product at an affordable price.
